Lisa’s “Money” took over the airwaves thanks to TikTok. The song addresses several economic concepts. First, currency is considered a medium of exchange, and cash is perfectly liquid. Understanding the important role that currency plays is critical to market transactions. Second, the sum of currency and checkable deposits are equivalent to the M1, Money Supply. Throughout the song, Lisa assures us that cash and her bank account support her lifestyle. Lisa provides several lines about her purchasing and spending behavior, supporting the definition of the velocity of money. Economists measure the velocity of money to examine how currency travels throughout the economy, measuring the quantity of exchanges.
Thanks to Brad Scott for the clip recommendation and summary!
In order for bartering to be a successful payment of transactions, both sides must want what the other is offering and be willing to trade for it. Unfortunately, the seen above shows the difficulty of meeting the condition known as double coincidence of wants. Even though the man has Johnny Cash headshots, the young entrepreneur is only willing to accept US cash.
US currency may say “In God We Trust” but in order for the bills to mean anything, we place our trust in the US government. US currency is a type of fiat currency (as opposed to a commodity money) that has the backing of the US government. In order for something to be considered money, it must serve three general properties: store of value, a unit of account, and a medium of exchange. Each can be seen in the clip above. A lemonade seller won’t accept just anything, they want money (medium of exchange). We know the price of the lemonade because we use dollars as a measure of its worth (unit of account) and we expect those dollars to be worth the same amount over a certain period time (store of value).
The Baudelaire orphans have been sent to the Lucky Smells Lumbermill and are being forced to work on the production floor. After a grueling morning of “log day,” the workers are given an entire five minutes for lunch, but the Baudelaire’s come to find that lunch consists of gum. Frustrated, they wonder if they can use their wages to buy something else, but it turns out that the Lucky Smells Lumbermill pays their workers in coupons rather than actual currency. The coupons don’t have any value since the workers don’t have any money to go out and buy things anyway. The workers also don’t have power to leave or demand better conditions because Lucky Smells is the only place to work in town.
When a single firm controls the labor market in a region, they are said to have monopsony power in the market. Monopsonies can pay workers below competitive wages because workers are unable to find alternative employment opportunities. In this case, the Lucky Smells Lumbermill pays them almost nothing since the coupons can’t really be redeemed anywhere.
The gang tries to catch a leprechaun for St. Patrick’s Day so that they can get his three wishes. In their quest, Beast Boy uses one of his wishes to become a leprechaun and beings to “live the leprechaun life” which includes a lust gold. Beast boy sells all of his friend’s stuff in exchange for gold. He then announces that his goal is to get the government back on the gold standard and attempt to fix the exchange rate. They go on to explain the rationale behind the gold standard and Nixon’s authorization to end the gold standard.
Loralei is seeking to take over the world and she wants money, but Rooster shows up with a bag full of paper money instead of gold. Rooster explains to her that on Earth, paper money is just like gold although he mistakenly says that Ben Franklin was a US president. While dollars used to be based on gold, they have since been converted to fiat money is backed on faith of the US government.
In this animated short from the Walt Disney Company, Uncle Scrooge discusses the history or money and the importance of money in the overall economy. There are A LOT of great teaching opportunities in this clip and would make a great summary of a money supply lesson or a required video to be watched before the lesson.
Opening to 7:15 History of Money Huey, Dewie, and Louie visit Scrooge McDuck and request that he help them save the money they had earned. Scrooge goes through the history of money and discusses the role of salt as the original salary that Roman soldiers received. He then goes on to describe money from other societies and why money was important following original barter economies. The characters even discuss the role of money as a medium of exchange!
7:15 to 9:59 Inflation After learning of the importance of money in the economy, the brothers question why central banks don’t just print more money if everyone wants it. Uncle Scrooge discusses the role of fiat money and why it’s important for the money to be backed by something or someone who can promise to pay the notes that are printed.
10:00 to 13:20 Financial Planning and Taxes Uncle Scrooge teaches the brothers about the importance of budgeting. People need to make sure that they allocate a portion of their income toward rent, food, and other necessities. He also teaches them about the role of taxes and how important it is for governments to have a budget and make sure that they collect taxes to pay debt.
13:20 to End Velocity of Money & Investment The boys are curious why Scrooge keeps so much money in his vault if he tells them that it’s important to put money “to work.” He teaches them that the money in his vault is just his petty cash and then goes on to discuss the importance of money circulating through the economy. The ending portion discusses the role of corporations issuing stocks and shareholders collecting dividends. At the end, he signs the boys up to manage their funds, but charges them a fee. The boys aren’t happy, but he laments that “nothing is ever free.”
In this Super Bowl ad, a bar patron tries to pay for a round of drinks with a lawn mower, but this has apparently been an issue before as the bar has a sign that lawn mowers aren’t accepted. This clip is a good, quick introduction to the role of money in an economy and why bartering would be hard to accomplish.
Homer laments of his problem of having no money and three children, but would instead prefer no kids and “3 money.” Kids, thankfully, cannot be used as money, but do represent a tradeoff in that parents could spend their money on other items instead.
Vox takes a deeper look into the use of ramen as currency inside America’s prison system. Ramen serves a unique function as money since actual cash isn’t allowed in prisons. In order to serve as currency, an item needs to be durable, portable, and standardized, which ramen is. Ramen is the largest item purchased in prison commissaries and once inmates stockpile ramen, they can inflate/distort prices for other goods and services in the prison. The use of Ramen in prison economies is also mentioned in Brooklyn 99.
